There's a difference between the game still stinging and still actively rooting against a team that beat your team in a game played in 1998 (the definition of butthurt). Still hate seeing highlights from XXXII, but I haven't cared one bit about the fortunes of the Broncos for about 15 years.
I actively root against DEN, SF and SEA. Oh, yeah, and DAL, and NYG. CHI, DET and MIN. STL, PHI, ATL. NE.
